%X The preparation and speciation distribution characteristic of a new kind of inorganic polymer flocculant(IPF)-PFSi were investigated in detail by the combination of direct and indirect speciation analysis methods. The experimental results show that the speciation distribution of PFSi is decided significantly with basicity, kinds of silica and Si/Fe ratio. Among them, the basicity is one of the main factors. SilicaA and silicaB exhibit a similar effect, while silicaC has limited effect on the hydrolysis of Fe(III). The typical speciation distribution and transformation property of PFCl changes limitedly with the introduction of silica species.
